Greenhouse winch handle 1” D (25 mm)
The tunnel winch is a small, but very important mechanism of the greenhouse.
This handle is an option for the hobby greenhouses with ventilation as well as for professional greenhouses, allowing the manipulation of weathering. Film curtains, which are part of the entire relief (ventilation) system, are raised and lowered by the greenhouse winch. Ventilation in a greenhouse is an important process for the proper development and growth of plants. Excess heat and moisture are removed beyond the barrier, rolling up the cover. The handle consists of steel tubes with a diameter of 22 x 1.5 mm, 25 x 1.0 mm and 28 x 2.0 mm.

Galvanized tunnel elements
The tunnel winch handle, like other greenhouse elements, is covered with a layer of zinc applied by hot-dip galvanization. This protects the elements from corrosion. Some of the parts exposed to ambient atmosphere are particularly exposed to corrosion. This is how steel is protected against corrosion, which guarantees long life of the entire assembly.
